[Bug]: List backend calls return objects without kind

[lucferbux]

Is there an existing issue for this?

• I have searched the existing issues

Deploy type

Installing Dashboard directly (eg. v2.12.0, commit xyz, branch name)

Version

main

Current Behavior

As per k8s design, listing resources returns objects without kind attribute.
This is addressed in the pass-through library by adding the type to each object in the list.
We need to add this logic to backend list calls to even the resources.

Expected Behavior

When listing k8s resources, all calls should return the same attributes.

Steps To Reproduce

1. Go to the Settings Panel
2. Navigate to Custom Serving Runtimes
3. Open the Network inspector in Chrome
4. Check that the call to list templates return objects without kind
